Feed for bi rds in
alternative production
Energy
The main difference between cage and alternative
production feed is energy requirement. Birds in alternative
production system are much more active and when they
have access to the range are confronted by temperature
variations. These two factors lead to an increase in
their energy requirement. To cover their higher energy
requirement, birds eat more. According to the housing
system used, temperature and bird feathering, feed
consumption can be increased by 3 to 20%.
